' of the pulleys 5 or 6.

To aZZ whom it may concern.-

Be it known that I, AMOS WOEBER, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented. certain new and useful Improvements in Plating-Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has relation to plating-machines; and it consists in thenovel construction and arrangement of parts, as hereinafter described.

The machine is especially designed for platin g or drawingout plowsharesand cultivatorshovels. The machine is provided with a reciprocatingtable upon which the die is located. The die is adapted to hold thearticle to be plated, and the reciprocatingtable passes under a roll,the roll coming incont-act with the upper side of the article andplating the same. The machine is provided with asuitable device forlifting the plated article out of the die and casting the same away fromthe machine. The article thus treated is smoother and more uniform thana similar article plated under a hammer. The machine enables a greatnumber of articles to be treated. Thus the process is shortened, and itis not neces sary for the operator to face the excessive heat.

In the accompanying drawings, Figure 1 is a top plan view of themachine. Fig. 2 is a side elevation. Fig. 3 is a longitudinal sectionalView ofthe machine. Fig. 4 is a transverse sectional viewof the machine.Fig. 5 is a rear end View of the machine, the upper portion beingremoved. I

The base 1 is provided on opposite sides with the uprights 2 2. Thehorizontal shaft 3 is journaled in the uprights 2 2. shaft 3 is providedwith a fly-wheel 4 and at the opposite end with a fixed pulley 5 and aloose pulley 6. The machine is operated by means of a belt adapted topass around either The shaft 3 is also provided with the smallgear-wheels 7 7, said gearwheels being located beyond the outer sides ofthe uprights 2 2. The gear-wheels 7 '7 mesh with the large gear-wheels 88, the said gearwheels 8 8 being attached to the ends of the of thebearings 10 10.

r or lowered.

The said shaft 9, the said shaft 9 passing through the journals 1O 10and supporting the roll 11. The bolts 1212 are externally threaded andpass through internally threaded perforations in the caps 13 13, thelower ends of the bolts 12 12 being journaled to the upper sides 7 Thusby turning the bolts 1212 the bearings 10 10 may be raised One end ofthe roll 11 is cut away, as at 14, and is provided With a roundedshoulder 15, said shoulder extending half way around the periphery ofthe roll 11. The cutaway section 14 also extends half-way around, asindicated in Fig. 3. The function of the cut-away section 14. will behereinafter explained.

At the right-hand side of the machine the the shaft 17. A clutch 18 islocated on the shaft 17. The said clutch is adapted to be operated bythe lever 19. The clutch when engaging the hub ofthe wheel 16 makes thesaid wheel rigid with the shaft 17. The shaft 17 is provided with theeccentrics 20. The pitmen2l at one end surround the eccentrics 20, asshown in Fig. 3, and at their other ends are connected to thereciprocating table 22. The rollers 23 are adapted to work on the upperface of the base 1, the shafts of the rollers 23 being journaled in thesaid arms 24. The reciprocating table 22 rests upon the upper portionsof the rollers 23, as shown in Fig. 3. The upper face of the table 22 isprovided with a number of ordinary bolt-slots 25. A

die 26 is located on the upper surface of the table 22, and the said die26 is held firmly in position by means of a number of bolts 27, whichpass through suitably-perforated lugs attached tothe die 26,the lowerends of the bolts being secured in the slots 25, as shown means of abolt 30, as shown in Fig.. 3. In. I

said figure, 31 represents an article located in the upper recess of thedie, the plate 29 coming in contact wit-h the rear edge of the article31, thus holding it in position. The upperedge of the plate 29 isprovided with the recesses 32, (see Fig. 5,) the function of which willbe hereinafter described. The rear edge of the table 22 is provided withthe rearwardlyextending arms 33, between the ends of which is journaled'a roller 34. At the back of the machine the horizontal rod 35 isjournaled. The said rod 35 is preferably squared and is adapted to carrythe fingers 36, the fingers 36 extending up from the rod 35, the forwardends of the said fingers being substantially horizontal, as shown'inFig. 3. The upper sides of the fingers 36 are provided with the lugs 37and the forward ends 38 of the fingers are pointed. A set-screw 39 holdsthe fingers in their proper positions upon the rod 35. The rod 35 isprovided with a weight 40, the said weight being adapted to hold the rodand the fingers 36 in their normal positions.

The machine is operated as follows: A suitable die is secured to theupper face of the table 22. The belt supplying the power to the machinesurrounds the fixed pulley 5. Thus the shaft 3, the fly-wheel 4., thegearwheels 7 7, the gear-wheels 8 8, and the roll 11 are rotating. Theclutch 18 is disengaged from the hub of the wheel 16, and thus the shaft17 and the table 22 are at rest. The article to be plated is placed inthe upper recess of the die 26, and when the roll 11 is in the properposition the operator manipulates the lever 19 and throws the clutch 18into engagement with the hub of the wheel 16. Thus the shaft 17 iscaused to rotate, and the eccentrics 20, through the pitmen 21, causethe table 22 to pass over the friction-rollers 23.

and thus carries the die 26 under the roll 11,

the periphery of the roll coming in contact with the article located inthe recess 28. The upper surface of the said article is plated when theplate 29 is advanced far enough, the pointed ends 38 of the fingers 36entering the recesses 32 of the plate 29, the ends 38 of the saidfingers passing under the article just plated. The roller 34 passesunder the under sides of the fingers 36, and when the said roller comesin contact with the end of the curved surface 41 (see Fig. 3) of thesaid fingers 36 the ends 38 of the said fingers are elevated, and thusthe article is lifted from the die 26 and is thrown away from themachine, the lugs 37 preventing the article from slipping along theupper sides of the fingers 36. As the table 22 and the roller 34 passfrom the front of the machine the Weight 40 will entire upper surface ofthe article, the lower portion of the roll 11, as shown in Fig. 3, isused. WVhen it is desired to perform what is generally known ascenter-plating, the upper portion of the roller, as shown in Fig. 3, isused. To accomplish this, the operator manipulates the lever 19 at theproper time to bring the article located in the die 26 in contact witheither the upper or lower portions of the roll 11, as shown in Fig. 3.In centerplating a cutting-knife is used. (This knife is not shown inthe drawings.) The knife is generally brought to the middle of theroller, and the end of the article being treated projects beyond therounded shoulder 15 and remains in its original state, while the balanceof the article is plated and trimmed. In plating plowshares the straightside of the roll is used, and thus the share is plated along its entireupper surface at one time. The recess 28 in the die 26 may be providedat its forward edge with an inclined surface, as shown in Fig. 3, andthus the edge of the article may be tapered and plated at one operation.

Having thus-described my invention, what I claim as new, and desire tosecure by Letters Patent, is I 1. In a machine such as described,a rollsuitably j ournaled, a reciprocating table adapted to pass under saidroll, a die carried by said table, suitable recesses located in the backof the die, fingers adapted to pass through said recesses and beneaththe article in the die, a suitable means for elevating said fingers andlifting the article from the die, a suitable means for operating theroll and the table.
